Filling 'and Empt mg Vessels, 'of which the tollowing is a ful clear, and exact description, reference being had to the accompanying drawings. f Y

lhis invention relates to devices for filling and emptying vessels of liquid, the invention working upon the rinciple 'of an ejector and havin for its o ject the production of a device w ich shall be 'eiiicient and rapid in its operation, convenient in usage 'and inexpensive in construction.

In thedrawings .forming a part hereof, Figure '1 isa 'general persfljective view showremptying atub 'of 'water'or'other liquid; Fig. 2 isa 'longitudinal ysection through fthe center vof the in'- vention; and Fig. 3 is a fragmentary sectional view showing a somewhat modied form of my invention. A

Takinglup la'detailed description by-referenceto t e drawings, l vrepresents al tub, or any otheryessel that is to be filled andvemptied. -2 isa `liexible pipe', which lmay be an ordinary hose-'pi e, that 'is adapted to lbe inserted at .one en into the tub, the opposite end of which 'is attached to a curved tubular rejection?) on the outer ejector member 4. xihis ejector member has a longitudinal opening 5 extending therethrough," said opening being expanded' at 6 opposite `the tubular extension 3. Above the enlarged i portion 6, theouter 4member 4 is closed at 7,

except for a comparatively small central aperture which is threaded for the reception ofv they nozzle 8 which screws into said'` aperture. This nozzle has a central longitudinal opening extending throughout its length and gradually diminishing in size toward its in-` -ner end. At its puter end the' nozzle is prof vided with a flange or head '9 for engaging with a nut or union 10, by means of which the nozzle and the ejector` may he attached to an ordinary cock or splgot 11, said splgot being connected in the usual way with a. vsource of fluid supply.

aria lower end, es ehem in Fi .2,7m

Aimiter member 4 is Ascrew-t eaded,

`and tothe said end there is screwed a valve lcasing 12 havin an opening 13 there- -l'hrough in axial a inementwith the opening 5in the outer ejector memberf J ournale'd withirifthe valve casing is a valve 14, havin a passage 15 therethrough, which is adapte to be turned so as to open or close the passage 13 in the usual manner. The lower end of the casing'12 isv provided with ratchet corrugations 16 so as to adapt'theI samejior holding a hose pipe which may be attached A thereto. Similar ratchet corrugations, 1-7 are also formed on thetubular extension 3 for holding the hose pipe 2. The nozzle 8 projects into the enlarged part 6 of 'the central bore of the member 4 and extends substanti'ailr` to the lower portion ofthe passage" Jthrough the tubular extension 3.

From the above description it will be understood that when the valve 14 is closed and the valve inthe spigot 1l iSjOp'en, thew'atter or 4other li uid will pass intothe'e'ector member '4 t rough 'the nozzle -B and t-"e'ne,

upwardly through the tubular 'extension 3 and the hose ipe 2 into the tub or vessel 1 thus filling t e vessel. When it is desired to empty the tub, it is only necessary to open the valve 14 and the valve in the spigot 11, when the liquid will rush through the nozvzle -8 and through the valve casing, thereb drawing. by suction theliquid from the tu through 'the hose -2 and the tubular extension 3. Tt'will be seen, therefore, that b simply opening 'and closing the valve 14 am enabled to control the direction of flow ofthe liquid in the hose pipe 2 and to thus .till or -empty the tub 1 as desired.. The suction produced yby the flow of the li uid through the l'nozzle 'fis suilicient to. ligt through the pipe 2 for 'aoonsiderable distance, so that the relative positions 'of the ejector and vthe/vessel may be varied through wide limits. /In the drawin l have shown.

the water the tub 1 .as/elevated above t e ejector rand,

'1"2 and 'theli uid. led :away -to anyl suitable place, but .in ifg. 1 I have 'shown t e ejector directly over a catch 'basin 18, in 'which sition Tno pipe )is used. 'on the lower fend of the casing 12.l It will be evident, however, that the pipe 16l will lower the ultimate outlet from the vessel, and that the siphonic action willl be increased by the use of such ge valve shown in Fig. 2 is -the ordinary form of ta ered cylindrical valve. f In Fig. 3 I haves own a' somewhat modified form of construction, in which 4 represents the lower part of the outer ejector member and At its lower 5a the opening, therethrou h. end the sald openingis o larger diameter 'in order that ,an iiat disk-valve 19 may be inserted through ythe lower end of the mem ber 4a and he d in position by a' pivot rod 20, this valve and rody being similar in construction and operation to the ordinary rotary dam er used in stove pipes. In Fig. 3 the full hnes represent vthe valve in closed position, its open position being indicated .broken lines. Such avalve possesses the advantage`v of cheapness of manufacture overv the valve shown in Fig. 2, and while there 'may bea slight leakage of liquid about the ter, especially valve, this is not, regarded as a serious matin case water is employedl for operatmg the ejector.

I claim:

1. The combination with a vessel that is to be filled with or emptied of a liquid, of

, member beyond the oint at-which the said t closin 'a pipe leading t`o said vessel, an ejector to which the outer end of the pipe is attached, andl means for closin the ejector beyond its connection with sald pipe, whereby the liquid owing into the ejector may be forced through the pipe into the vessel. v

2. Thecombination with avessel .that isto be filled with or emptied of 'a liquid, of a pipe leading to said vessel, an ejector to which the outer end ofthe pipe is attached, and a valve for closing the ejector beyond its connection with said pipe, whereby the liquid flowing into the ejector may be forced through the pi e into the vessel, or, by o enl ing the valve, t

e liquid-may be drawn rom the vessel.

3. The combination with a vessel to be lled with or emptied of a liquid, of a pipe having one end projectin into said vessel, an ej ectgr member to. whic the opposite end of the pipe lis attached,4 an ejector nozzleprojecting. into said member,` means for attaching sald nozzle toa source of fluid'sup-l ply, and means for closing the said ejector pipe is' attached, w Aereby when the said closing means is opened the liquidvwill ass through the ejector -and draw the'liqui by suction from the vessel and when the saidmeans is closed the liquidl will be.

force through the said' pi e into the vessel. 4. The combination wit a vessel tobe -filled with or emptied of a liquid, ,of a pipe lleadmg to`said vessel, an ejector member below the said vessel to which the'opposite end of `the pipe is attached, an 'ejector .nozzle projectmg'lntosaid member', meansv for atf:

tachng said nozzle to a source ofviiuid supply', and means for closing the said ejector member beyond the oint at which the said pipe is attached, w ereby when the said closing means is opened-the liquid will ass through the ejector and draw the liqui by suction from the vessel to start the flow,

.after which the source of fluid supply may be cut ofi' to permit the glow to` cntinue by siphonic laction, and when the said closing' means is closed the liquid will be force lthrough the said pipe into the vessel..

5. In an ejector, an outer member having a longitudinal opening therethrough, a tu- Y, 4

bular extension on said member having an o ening therethrough communicating with t e opening in the ejector member, a nozzle projecting into the ejector member substan.

tially opposite the tubular extension, means for attaching the said'. nozzle to a source of fluid supply, and a valve for closing the opening` in the ejector member, whereby liquid may be drawn into the lejector throu h the tubular extension or may be forceg outwardly therethrough. V

6. In an ejector, an outer member having a longitudinal bpening therethrough, a tubular extension on said member extending at an angle thereto and having an opening communicating with the opening. in the ejectormember, a nozzle projecting into the ejector member substantlally opposite the tubular extension, means for attaching the said nozzle to a source of fluid supply, and a valve forclosing the opening in the ejector member, whereby liquid may be drawn into the ejector throughthe tubular extension or may be forcedoutwardly therethrough.

7. The combination with a vessel that'is to l be filled with or emptied of a liquid, of a hose pipe leading to' the vessel, an ejector' member having a longitudinal opening therein, a tubular extension on said member having an opening extending therethrough and connecting with the opemn in the said member, said tubular extension eing adapted for attachment to the hose pipe, a nozzle secured Ato said member and extending with- 'in the opening therein to a point substantially opposite the inner'end ofthe tubular extension, a water-cock or spigot, meansfor attachin the nozzle to said cock or spigot, and a va ve for closing the' opening throu h the, ejector member beyond the end oft e nozzle, whereby., when the valve is opened,

the water from the spigot will draw the v tubular extension on said member having an.

the water will be forced into the .necting at an a opening extendin therethrough and icon'- e with the. opening in the seid member, said tubular extension being adapted for attahment to the hose pi s, nozzlelscrewing mto said member an ex-A tending within the opening therein toa point substantially opposite the inner endl of the' tubular extension, a water'- cock or spi ot, means for attaqhing the nozzle to sai cock or spigot, and a. valve for closin the opening in the ejector memberbeyon l, the end' of the nozzle, whereby when the valve yis opened, thel water from the spigot will draw'the liquidv from the vessel, and, when the valve is closed, the waterwill be 15 forced into the'vessel.

In testimony whereof, I hereunto aiix my signatl'lre in the presence of two witnesses.
